I'm going to the United Stated to attend my daughter's commencement .   How nice ! Are you going to convert some RIB to US dollars ?   Yes . But I will not take much cash with me I can ask the bank to give me the traveler's checks . So it will be safer .   How can you cash them when you arrive in the United States ?   I will go to the bank , give them my check , show them one piece of my identifications , and the most important thing is that I should sign my name to endorse the check .   It sounds quite simple . Next time when I travel abroad , I will apply for this kind of check too .
